[Cable Network News] In recent years, with the rapid development of the national economy, the demand for special cables has increased dramatically. The demand for special cables in the shipbuilding, railway, aircraft, aerospace, petroleum, chemical, metallurgical and nuclear power industries has increased year by year. Due to the expansion of the entire market capacity, special cables have also ushered in good development opportunities: oil drilling rigs demand more than 15,000 kilometers per year; high-speed rail demand exceeds 37,300 kilometers... and such as railway signal cables, marine cables, automotive wires Special cables such as mining cables and aircraft cables are growing at a rate of tens of thousands of kilometers per year.
Compared with ordinary cables, the competition in the special cable industry is more orderly and more promising. Because special cables are different from conventional cables, they need to be used for specific applications in specific occasions, requiring high temperature resistance, acid and alkali resistance, termite resistance, and corrosion resistance. Even resistant to radiation. In short, the high technical content, new application fields, and high barriers to entry are also conducive to the development and improvement of enterprises.
At present, the demand for special cables in China is increasing at an annual rate of nearly 20%. The development of special cable companies is on the rise. On the one hand, the competition for ordinary cables is intensifying, and on the other hand, the special cables are in the ascendant. Faced with the new pattern of the cable market, how to seize the opportunity and seize the opportunity has become a new topic facing the wire and cable enterprises.
The state advocates energy conservation, emission reduction and green development, and also provides new development opportunities for special cables. Such as the national smart grid construction, from planning, demonstration to step-by-step implementation, each step is inseparable from special cables. The large-scale transformation of urban and rural power grids, the application of high-voltage ultra-high-voltage cables, the construction of new energy power stations and the special needs of other emerging fields have also injected vitality into the development of the special cable industry.
The gradual increase in domestic demand has brought a huge market to the special cable industry. And in line with the international market, it gives the opportunity of the special cable industry. As China joins the WTO and becomes a factory in the world, the speed of integration between the domestic economy and the world is gradually accelerating. The vision of special cable companies has also been released from the domestic market.
Since the development of special cables in Europe and the United States started earlier than half a century in China, it is in a relatively leading position both in terms of experience and technology. However, the pursuit of China's special cables is also extremely rapid, such as military special shielded cables, aerospace silane cross-linked wire and cable, high-temperature high-conductivity transmission cables, etc., have now got rid of foreign technology monopoly. 'In terms of cables with special uses and structures, China may still have a gap with Europe and the United States, but in terms of high temperature resistance, green insulation and functionalized cables, we can almost equalize with foreign countries.
Faced with broad development prospects and fierce market competition, the special cable industry urgently needs to develop a development path that suits itself. In the “Twelfth Five-Year Plan”, the state has put forward new requirements and support for the special cable industry, which also provides an opportunity for the transformation and upgrading of the special cable industry. As a high-tech representative in the cable industry, special cables can only continuously improve the technological content of the products and the core competitiveness of the market through innovation and technology.
At present, there are more than 500 enterprises engaged in the production of special cables in China. Although some enterprises in the province, such as Henan Huatai Special Cable, have entered the domestic advanced level from technical equipment, testing methods, financial strength and product performance, Overall, the technical level of the special cable industry is still not competitive internationally.
The flaws in technology that are not top-notch and insufficient in capacity cannot be ignored. Taking high-speed rail and oil-mining rigs as an example, the annual capacity gap is tens of thousands of kilometers. At the same time, the supporting special cables for emerging energy technologies such as heat radiation and photovoltaics are also seriously insufficient. A person in charge of a special cable in the province believes that the start of special cables in China is different from ordinary cables, and it is still relatively young, which has also caused the lack of specialization in related fields. In the vacant market, competitors will not give up, only through innovation to fill the gap, in order to withstand the pressure in the current situation, expand market space and corporate competitiveness.
The secret to the success of special cables lies in technology and technology. Raw materials have always been a bottleneck restricting the development of special cables. China's cable industry needs about 4.4 million tons of copper and 2 million tons of aluminum per year.
According to statistics, the annual output value of China's cable has exceeded one trillion, of which copper core cable accounts for 97%. Such a huge amount of copper used to bring certain support to the price of copper, and the production cost of cable manufacturers has also remained high. Once the international copper price fluctuates, domestic special cable manufacturers will often be affected. This requires us to look for related alternatives.
Today, the high-strength and high-conductivity rare-earth copper alloy has become a new type of high-conductivity material, and the comprehensive performance of the alloy has been balanced by hot rolling, solution treatment, cold rolling, aging and other processes. The electrical conductivity, tensile strength and hardness are significantly improved compared with the traditional process; 'two feet walk better than one foot. The special cable industry continues to maintain and develop copper cables, and the large-scale production of new materials At the same time as solving technological innovations from raw materials, enterprises also need to work hard on standardization.
Throughout the world's leading cable companies, all have international standards. In order for China's special cable to win an active position in international competition and achieve greater development, it is necessary to use collective power to actively strive for opportunities for standardization, and to understand and strive to become participants and even setters of the rules. Combine cable standardization with standardization requirements, better reflect the needs of standardization work in the enterprise and cable fields to industry standards, promote the development of enterprises and industries, and enhance the competitive advantages of enterprises and industries.
